Three-dimensional identification of stem cells by computational holographic imaging.
We present an optical imaging system and mathematical algorithms for three-dimensional sensing and identification of stem cells. Data acquisition of stem cells is based on holographic microscopy in the Fresnel domain by illuminating the cells with a laser. In this technique, the holograms of stem cells are optically recorded with an image sensor array interfaced with a computer and three-dimens...
متن کاملDigital holographic three-dimensional imaging spectrometry and depth imaging properties
We have studied a method to obtain both three-dimensional (3-D) spatial information and spectral information of a usual polychromatic object simultaneously by making use of a specifically designed two-wavefront folding interferometer and signal processing, including synthetic aperture technique, spectral decomposition, and 3-D image retrieval. The method uses only interferometric techniques and...
متن کاملHolographic Three-Dimensional Computer-Aided Imaging
Recent developments in a new method of holographic computer-aided imaging are reviewed. The proposed hologram is computed from angular viewpoints of the observed three-dimensional scene. The recorded data are processed to yield a two-dimensional computer-generated hologram. When this hologram is illuminated properly, a threedimensional image of the scene is reconstructed.
متن کاملThree-dimensional computational holographic imaging and recognition using independent component analysis
We present computational holographic three-dimensional imaging and automated object recognition based on independent component analysis (ICA). Three-dimensional sensing of the scene is performed by computational holographic imaging of the objects using phase-shifting digital holography. We used principal components analysis to reduce data dimension and ICA to recognize the three-dimensional obj...
متن کاملThree-dimensional polarimetric computational integral imaging.
In this paper, we propose a novel 3D polarimetric computational integral imaging system by using polarization diversity of objects under natural illumination conditions. In the system, the measured Stokes polarization parameters are utilized to generate degree of polarization images of a 3D scene. Based on degree of polarization images and original 2D images, we utilize a modified computational...
